Impact of psychological capital on construction worker safety behavior: Communication competence as a mediator.

Abstract

INTRODUCTION\nConstruction workers face a work environment of high risk and mental stress. Psychological capital (PsyCap) could influence employee s mental health and work performance. It would be helpful to determine whether PsyCap affects worker safety behavior. However, few studies empirically examined the impacts of the sub-dimensions of PsyCap on the safety behavior in construction settings, reducing the potential practicability of PsyCap to improve workplace safety performance. Thus, this study tested the relationship between sub-dimensions of PsyCap (self-efficacy, hope, resilience, optimism) and safety behaviors (safety compliance, safety participation), while the mediating role of communication competence was also explored.\n\n\nMETHOD\nData were collected from 655 construction workers in China using a psychological capital questionnaire (PCQ). The theoretical model were tested with confirmatory factor analyses (CFA) and structural equation modeling (SEM) techniques.\n\n\nRESULTS\nResults show that: (a) the self-efficacy dimension of PsyCap positively affected safety compliance and safety participation, while the resilience dimension positively impacted safety participation; (b) the hope dimension was not directly related to safety behaviors, while the optimism dimension negatively associated with safety participation; and (c) communication competence mediated the relationships between the hope and optimism dimensions of PsyCap and safety participation.\n\n\nCONCLUSIONS\nA multidimensional perspective on PsyCap should be taken while examining its effects on safety behavior and the individual communication competence helps to enhance construction safety. Findings of this study shed lights on safety behavior promotion practices based on the multidimensional model. Initiating flexible psychological capital training and intervention, and strengthening communication skills of construction employees are suggested to improve safety performance in the construction industry.
